Movie /book/song that chnaged your perspective on something? how?

After watching the Hotel Rwanda movie it really enlighted me about the thing that were going on in Africa and how people were suffering and being killed every single day. The movie was about a war going on between two tribes in Rwanda. Everything that was in the movie was based on true events that happened. Women, the elderly and children were all being slaughtered because they were from the wrong tribe. This movie taught me to be thankful for what i have in America. My freedom, my safety, and everything else that those people in Rwanda dont have. It also taught me that nothing should ever be taken for granted.
